Question:
How do I allow the user to make my application the default handler for a MIME type?

Answer:
If you are going to allow the user to alter which application controls a certain MIME type then a suggested method is to provide a function somewhere in your AppUi class along these lines:

{
CTypeStoreManager* db = CTypeStoreManager::NewL(iEikonEnv->FsSession());
CleanupStack::PushL(db);

_LIT8(KMimeType, "some/mime-type");

// EOF is an expected error if the file does not exist...
TRAPD(err,db->RestoreL());
if (err != KErrNone && err != KErrEof)

{
User::Leave(err);
}

db->InsertDataMappingL(TDataType(KMimeType)

,KDataTypePriorityUserSpecified
,Application()->AppDllUid()
);

db->StoreL();

CleanupStack::PopAndDestroy(); //db
}
